ATOS電磁閥里有密閉的腔，在不同位置開有通孔，每個孔連接不同的油管，腔中間是活塞，兩面是兩塊電磁鐵，哪面的磁鐵線圈通電閥體就會被吸引到哪邊，通過控制閥體的移動來開啟或關閉不同的排油孔，而進油孔是常開的，液壓油就會進入不同的排油管，然后通過油的壓力來推動油缸的活塞，活塞又帶動活塞桿，活塞桿帶動機械裝置。這樣通過控制電磁鐵的電流通斷就控制了機械運動。 ATOS電磁閥主要分類： 1、ATOS電磁閥從原理上分為三大類(lei)： 1）ATOS直動式電磁閥： ATOS電磁(ci)閥原理：通電時，電磁(ci)線圈產生(sheng)電磁(ci)力把關(guan)閉(bi)(bi)(bi)件從閥座上(shang)提起(qi)，閥門打開(kai)；斷電時，電磁(ci)力消失，彈簧(huang)把關(guan)閉(bi)(bi)(bi)件壓在(zai)閥座上(shang)，閥門關(guan)閉(bi)(bi)(bi)。 ATOS電磁閥(fa)特點：在真空、負壓(ya)、零壓(ya)時能(neng)正常工作，但通(tong)徑一般不超(chao)過25mm。 2）分步(bu)直動式(shi)電磁閥： ATOS電磁閥(fa)(fa)(fa)原理(li)(li)：它是(shi)一種直動和先(xian)導式相結合(he)的原理(li)(li)，當(dang)(dang)入(ru)口與(yu)出口沒有(you)壓(ya)(ya)(ya)差(cha)時，通電后(hou)，電磁力(li)(li)直接把(ba)先(xian)導小閥(fa)(fa)(fa)和主閥(fa)(fa)(fa)關閉件依次向上(shang)提起(qi)，閥(fa)(fa)(fa)門(men)(men)打(da)開。當(dang)(dang)入(ru)口與(yu)出口達到啟(qi)動壓(ya)(ya)(ya)差(cha)時，通電后(hou)，電磁力(li)(li)先(xian)導小閥(fa)(fa)(fa)，主閥(fa)(fa)(fa)下腔壓(ya)(ya)(ya)力(li)(li)上(shang)升(sheng)，上(shang)腔壓(ya)(ya)(ya)力(li)(li)下降，從而利用壓(ya)(ya)(ya)差(cha)把(ba)主閥(fa)(fa)(fa)向上(shang)推(tui)(tui)開；斷(duan)電時，先(xian)導閥(fa)(fa)(fa)利用彈簧力(li)(li)或(huo)介質壓(ya)(ya)(ya)力(li)(li)推(tui)(tui)動關閉件，向下移動，使閥(fa)(fa)(fa)門(men)(men)關閉。 ATOS電磁閥特(te)點(dian)：在零壓(ya)差或真(zhen)空、高壓(ya)時亦能可*動作，但功率較大(da)，要求必須水平安(an)裝。 3）先導(dao)式電磁(ci)閥： ATOS電(dian)(dian)磁閥原理：通電(dian)(dian)時(shi)，電(dian)(dian)磁力把(ba)先(xian)導孔(kong)打(da)開(kai)，上(shang)腔室壓(ya)力迅(xun)速(su)(su)下(xia)降，在(zai)關(guan)(guan) 閉(bi)件(jian)(jian)周圍(wei)形成(cheng)上(shang)低下(xia)高(gao)的壓(ya)差，流體壓(ya)力推動(dong)關(guan)(guan)閉(bi)件(jian)(jian)向(xiang)上(shang)移(yi)動(dong)，閥門打(da)開(kai)；斷(duan)電(dian)(dian)時(shi)，彈簧(huang)力把(ba)先(xian)導孔(kong)關(guan)(guan)閉(bi)，入口壓(ya)力通過旁通孔(kong)迅(xun)速(su)(su)腔室在(zai)關(guan)(guan)閥件(jian)(jian)周圍(wei)形成(cheng)下(xia)低上(shang)高(gao)的壓(ya)差，流體壓(ya)力推動(dong)關(guan)(guan)閉(bi)件(jian)(jian)向(xiang)下(xia)移(yi)動(dong)，關(guan)(guan)閉(bi)閥門。 ATOS電磁閥特點：流(liu)體壓力范圍上限較高，可任意安(an)裝（需定制(zhi)）但必須滿(man)足(zu)流(liu)體壓差條(tiao)件。 2、電(dian)磁閥(fa)從閥(fa)結(jie)構(gou)(gou)和(he)材(cai)料上的不同與原理上的區別，分(fen)(fen)為六個分(fen)(fen)支(zhi)小類(lei)：直(zhi)(zhi)(zhi)動(dong)膜片結(jie)構(gou)(gou)、分(fen)(fen)步直(zhi)(zhi)(zhi)動(dong)膜片結(jie)構(gou)(gou)、先導膜片結(jie)構(gou)(gou)、直(zhi)(zhi)(zhi)動(dong)活(huo)塞結(jie)構(gou)(gou)、分(fen)(fen)步直(zhi)(zhi)(zhi)動(dong)活(huo)塞結(jie)構(gou)(gou)、先導活(huo)塞結(jie)構(gou)(gou)。 3、電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)按照功能分類：水用(yong)(yong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、蒸汽電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、制冷電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、低(di)溫電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、燃氣(qi)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、消(xiao)防電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、氨用(yong)(yong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、氣(qi)體電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、液(ye)體電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、微型電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、脈沖電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、液(ye)壓電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa) 常開(kai)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、油用(yong)(yong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、直流電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、高壓電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、防爆(bao)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)等。 意(yi)大利ATOS電磁閥型號表： DHU-0610/A-X 24DC 20
